Abstract
Background: Brachial plexus block is a valuable adjunct to general anesthesia for surgery of the upper limb and a suitable alternative in poor risk patients for general anesthesia. However, over the past 20 years, several studies have suggested that the addition of certain opiates to the local anaesthetics which are used for brachial block may provide effective, long-lasting postoperative analgesia. We designed this randomized single blinded prospective study to compare the analgesic efficacy of Fentanyl used as an adjuvant to ropivacaine for supraclavicular brachial plexus block in patients undergoing orthopaedic surgeries of forearm. Methods: For this randomised prospective, single blinded study 60 ASA I and II patients aged 20-60 were included and were divided into 2 groups, group A(30) and B (30). Supraclavicular brachial plexus block was performed in the group A using 0.75% ropivacaine 30 ml plus 5 ml NS (total 35 ml) and in group B received 0.75% ropivacaine plus 2micrograms/kg fentanyl in 5 ml NS (total 35 ml) in brachial plexus block. The onset time of analgesia, duration of analgesia were recorded. Results: Demographic parameters and block onset time were comparable in both groups. Regarding the mean onset time there is a statistically significant differencebetween the two groups(p < 0.001) .Regarding the mean duration of action is concerned there is no statistical significant difference between the two groups (p >0.05) . Conclusions: So addition of Fentanyl to ropivacaine produced a quicker onset compared to the plain ropivacaine.
